Guys, I have a question about different failure modes in FreeRadius, basically I want to differentiate between different scenarios of failures and return a proper response (if any) to NAS device. Failure example: Backend database is down Right now FreeRadius returns reject to NAS rlm_sql (sql): Failed to connect DB handle #8 rlm_sql (sql): reconnect failed, database down? rlm_sql_getvpdata: database query error [sql] SQL query error; rejecting user rlm_sql (sql): Released sql socket id: 8 ++[sql] returns fail Sending Access-Reject Say I do not want to return reject in this case and I want the switch to understand that radius is down and retry another radius server (a backup/failover). Because if I return reject the NAS device treats this as radius is UP and running. What is recommended behavior for Radius for: DB is down,Authentication infra is down(say kerberos is down)? Should it return REJECT or NOOP? Thank you very much for your responses. Leopold -- View this message in context: http://www.nabble.com/Freeradius-2.1-1%3A-failure-modes-tp22413666p22413666....
